About this map

Vale Valley defines the northern reaches of this Malheur County landscape, where the intersection of Cairo Blvd and Railroad Ave marks the small community of Cairo. The terrain transitions from the lowlands of the valley into the elevated Lincoln Bench and the expansive Big Sage Flats, carved by local drainages like Locket Gulch. This modern survey reveals a highly engineered agricultural landscape dependent on an intricate network of water management features, including the Ontario Nyssa Canal, Owyhee Ditch, and the Nevada Canal.

The southern portion of the map centers on the outskirts of Nyssa, showing the Nyssa Cem and the residential grid extending toward the Nyssa Drain. The reliance on irrigation is evident through numerous named laterals and drains, such as the North Canal Lateral and Valley View Drain, which support the farms of this high desert region. Researchers will find a mix of family-named roads and established water infrastructure that has shaped the local economy for generations.
